[oe] [meta-oe][PATCH] opencv: Enable pkg-config .pc file generation

[Carlos Rafael Giani]

In OpenCV 4, .pc file generation is disabled by default. Yet, other
software such as GStreamer and FFmpeg rely on the .pc files during build
time configuration. Explicitely enable .pc file generation to make sure
pkg-config can be used for getting information about OpenCV.
